Trump said the shutdown "could be a long stay" and White House budget director Mick Mulvaney said it could drag on to next year. He declined to say how much he would accept in a deal to end the shutdown, stressing the need for border security. "The only way you're going to do it is to have a physical barrier, meaning a wall".
Trump stressed during the surprise visit to the Al Asad Airbase in Iraq that the American public was demanding a border fence.
The promise of a border wall was a central component of Mr Trump's presidential campaign. Roughly 420,000 workers were deemed essential and are working unpaid, while an additional 380,000 have been furloughed.
Smithsonian officials announced Friday that the 19 museums in Washington D.C. and New York City will not close in the event of the shutdown with unused "prior-year funds" and that they "will reevaluate the situation" after January 1.
"The president wanted the shutdown, but he seems not to know how to get himself out of it", the Democratic leaders added. At President Trump's urging, the House approved that package and inserted the $5.7 billion he had requested.
"Nancy is calling the shots", said the Republican president, suggesting that her opposition to his demand for wall funding had to do with Pelosi's need for votes to become speaker. That jump-started negotiations between Congress and the White House, but the deadline came and went without a deal.
Top Senate Democrat Chuck Schumer said at the weekend the president "must abandon the wall, plain and simple" to reopen the government.

Ghosn earlier told his lawyer that he had planned to shift the investment losses to the company but stopped short of doing so. Renault has been much more cautious, keeping him on as chairman and CEO and appointing Thierry Bollore as interim boss.
"I can't tell you when the government's going to be open", the president said in a Christmas Day video conference with representatives of all five military branches stationed in Alaska, Bahrain, Guam and Qatar, the outlet reports.
The partial government shutdown appears no closer to resolution.
The shutdown that began on Saturday - the third of 2018 - caused a lapse in funding for nine of 15 Cabinet-level departments and dozens of agencies, including the departments of Homeland Security, Transportation, Interior, Agriculture, State and Justice.
The Mikkelsen family from Denmark, who is in Washington D.C. for a one-week trip, told Xinhua that they were at first "nervous" about the potential impact of the shutdown, but later were relieved to find that the Smithsonian museums are still open. Many are on the job but must wait until after the shutdown to be paid again.
Trump insisted that he would not relent on getting funding for the wall.
Almost 80 percent of federal employees responding to a survey by the U.S. National Treasury Employees Union (NTEU) earlier this week said that they were "very concerned" about paying their rental and bills this month, and more than 85 percent said they were tightening their belts. Many rank-and-file workers have gone to social media with stories of the financial hardship they expect to face because of the shutdown.
"Most view this as an act of ineptitude", he said.
